A.T. Robertson Commentary Hebrews 13:22

"But I exhort you, brethren, bear with the word of exhortation, for I have written unto you in few words." — Hebrews 13:22 (ASV)

Bear with (ανεχεσθε). Present middle imperative (some MSS. have ανεχεσθα, infinitive) of ανεχω with the ablative, "hold yourselves back from" as in Col 3:13.

The word of exhortation (του λογου της παρακλησεως). His description of the entire Epistle. It certainly is that, a powerful appeal in fact.

I have written (επεστειλα). First aorist active indicative (epistolary aorist) of επιστελλω, old word to send a letter (επιστολη) as in Ac 15:20.

In few words (δια βραχεων). Common Greek idiom, here only in N.T. (from βραχυς, brief, short). Cf. δι' ολιγων εγραψα in 1 Peter 5:12.
